CARRIER FOR PACKAGE-FILLING.

SPECIFICATION forming part Of Letters Patent NO. 660,537, dated October 23, 1900. Application filed July 26, 1900. Serial No. 24,921. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE R. \VYMAN, a citizen of the United States of America, residing at East /Valpole, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Carriers for Package-Filling Processes, of which the following is a specification.

This invention relates to hand processes of package-filling, and has for its object the construction of a carrier adapted to be used in said processes for the reception of the box or container which is to be filled and which supports and protects the said container from injury during the various operations to which it is subjected in the process of filling it with material, shaking down the latter to condense its bulk, and in folding and gluing end sections of the package to close it, and, lastly, in subjecting it to endwise compression to insure the adhesion of the end-closing sections. The invention consists in a construction adapted to meet the above requirements, all as fully set forth in the following specification and pointed out in the claims.

In the drawings forming part of this specification, Figure l is a perspective view of a carrier constructed according to my invention. Fig. 2 is another perspective view of said carrier from another point of view. Fig. 3 is a perspective view of a carrier having a package therein, the end-closing sections of which have been folded down against supports provided therefor to permit the mechanical gumming of the end-closing sections. Fig. 4.- shows the carrier in sectional side elevation in position undera press in which the infolded and gummed end sections of the container are pressed together to insure their adhesion.

In the art of package-filling many machines have been constructed for performing the operation automatically, but these machines are expensive and must be run to their full capacity to be run economically. Both their cost and their capacity place them beyond the reach of many of the smaller manufacturers of products which are boxed in cartons of various dimensions. To meet the requirements of manufacturers of this class, I have devised a semimechanical method of package filling and sealing which is much more rapid than filling and sealing by hand, as now practiced by the smaller manufacturers, and involves only a comparatively small outlay for mechanical appliances. That process ormethod forms the subject of a separate application.

The subject of this invention, the carrier, may be used in that or analogous semimechanical or semi-automatic processes; and it consists in a rectangular construction, preferably of wood, whose inturned dimensions are substantially the same as those of the filled and sealed package, for which it serves as a carrierduring the various operations of filling and sealing the same.

As shown in the drawings, the carrier consists of two pieces a a, into which are dovetailed the pieces b b, the four pieces being glued together and strengthened by the rods .1), which pass through the ends of the pieces,

a a, which are extended beyond the pieces 1), as shown, and whose ends are headed down over washers in the usual manner to draw the said pieces Ct a together. Centrally between the two pieces a (t, on each of the pieces I), are secured by screws or otherwise the members c 0, whose upper ends are in the plane of the upper end of the carrier. These members serve as supports for two oppositely-located end-closing sections of the box or container during the gumming operations, and they may be of any shape at their upper ends which will best adapt them to the particular form of the end-closing section of the box to be used in connection therewith. In the drawings the box or container shown is only one of a number that are adapted to be used in the carrier shown, and the only change which would be required in the latter would be a change in the form of the support 0 for the end-closing sections d d of the container 6. If desired, the said supports 0 0 may be made integral with the pieces I) of the arrier or they may be made of metal instea of wood. The preferred construction, however, is that shown in the drawings and described herein.

The under side of the carrier is provided with a rectangular metal plate f, having a rectangular opening therein of somewhat smaller dimensions than those of the interior of the carrier. This plate is secured to the bottom of the carrier, as shown in Figs. 2

and 4, and provides a narrow ledge running around all sides of the interior of the carrier on which the container 6 rests when inserted therein. This ledge afiords a propersupport for the filled container during the various op' erations to which it is subjected during the process of filling and sealing it. g It serves a further purpose of protecting the bottom of the carrier and the bottom of the package or container from abrasion. While it is desirable that the platef should practically cover the exposed portions of the Wood at the lower end of the carrier to protect the same from Wear, it is not necessary that the ledge formed by the projection of this plate inward beyond the inner Wall of the carrier should extend around all sides of the latter. It would suffice if said plate projected inwardly only from two and preferably opposite sides thereof.

In the process of filling packages or containers by the use of this carrier a number of the: latter are provided, and an empty container having one end closed is placed in each carrier,with the end-closing sections of the container upstanding. These boxes or containers are then filled with material, shaken-down, and the two end sections 9 g are folded in, as shown in Fig. 3, the end sections cl (2 being thereby extended over the supports-c a therefor. The carrier is then passed under a gumming-wheel hand the gum applied tothe two sections cl d and across a portion of the in folded sections 9 g, if desired. The sections d dare then folded over the other sections and the carrier placed under a press 7 as shown in Fig. 4, and from thence the filled and sealed package is removed from the carrier and the latter sent back to the point of beginning to receive another container.

By means of this carrier packages of uniform size and having sharp edges and true rectangular shape may be filled and sealed much more rapidly than by the hand process and much more cheaply.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A carrier for the purpose described con sisting of a hollow rectangular structure adapted to receive a container, supports on oppositesides of the upper end of said carrier for outwardly-extending end-closing sections of said container, and a ledge at the lower'endof the carrier on which said container may be supported, which ledge extends inwardly beyondthe inner Wall of the carrier, substantially as described.

2. A carrier for the purposedescribed which consists of a hollow rectangular structure, adapted to receive a container, a metal plate secured to the lower end of said carrier, the edges of which project inwardly beyond the inner Wall of said carrier on one or more sides, and outwardlyprojecting supports on two opposite sides of the carrier at the upper end thereof, adapted to support end --closing sec tions of acontainer in saidcarrier in position for gumming, substantially as described.
